While playing co-op split screen. Halo: CE has kicked us out of the game. Completely restarted it and did not save any data. My brother and i had made it to " The Library" when half way through the chapter it went black and restarted. We hit resume thinking it would take us back to the beginning of the chapter. Nope. All the way back to the beginning. We checked our career info and found that it did not show that we did any chapters on legendary co-op. Needless to say this was very discouraging.
It did the same thing to me on Halo 2 Anniversary. I exited the game to try to get the Halo Channel app to show me the terminal I had found, and it restarted the whole mission. Not a total loss however, since I was only around 10 minutes in.
I’ve also got some similar issues. I was playing the Halo 2 Anniversary campaign, and made it all the way to the penultimate mission if I’m not mistaken (give or take a mission). Given that it was 0400hrs I got kinda sleepy and decided that I would pick it up in the morning. I woke up today and found that only the first two missions had been “completed” which is weird because I’ve got the achievements for completing levels. I’m curious to find out what will happen now.
Same, I completed all the levels on legendary up to 343 guilty spark, was just about to finish the level when I paused the game, when in resumed the game I was booted out the game, then when I reloaded the game I have been put back to the truth and reconciliation, the ga,e does not recognise I have done the other levels, however in the achievements app it says I have done 5 missions, I have achievements for doing the levels and for finding the skulls and terminals on the levels. I just want my game data back so I can carry on
